Gunner is acting funny and I'm kind of freaking out He has acted fine all day and this evening we went to the park for a bit like we normally do. It's not super hot out and we weren't there for long. We just went and let the kids play so he wasn't even really working...just sat beside me. For the past probably 30 minutes though he has been acting funny. He's in his crate and is just sitting there panting really really hard. I let him out and he just sat down and panted. I offered him water and he drank a bit but I have no clue what could be causing this fast panting for no apparent reason. Thoughts?
